  • Silicate-, borate-and phosphate-free cooling fluids based on glycols and having improved corrosion behavior
    Patent number: 6309559
    Abstract: The invention relates to a coolant concentrate comprising a) from 0.1 to 6% by weight of at least one monocarboxylic and/or dicarboxylic acid having from 4 to 16 carbon atoms in the form of alkali metal salts, b) from 0.02 to 2% by weight of a triazinetriiminocarboxylic acid in the form of its alkali metal salt, c) from 0.02 to 2% by weight of at least one hydrocarbon triazole, d) from 0.01 to 1% by weight of at least one soluble alkaline earth metal salt, e) if desired, up to 4% by weight of water, and f) glycols to 100% by weight, in each case based on the total weight of the concentrate.

  • Heat transfer medium based on alkylene glycols for solar units
    Patent number: 6093341
    Abstract: The invention relates to a concentrate for a heat transfer medium for solar units, comprisinga) from 45 to 98% by weight of triethylene glycol and/or tetraethylene glycol,b) from 1 to 55% by weight of 1,2-propylene glycol and/or ethylene glycol, andc) from 1 to 6% by weight of corrosion inhibitors.The concentrate is used in admixture with water for heat transport in solar units.

  • Low-viscosity coolant brines having improved corrosion protection
    Patent number: 6059996
    Abstract: The invention relates to low-viscosity, aqueous coolant brines based on inhibited alkali metal acetates and/or formates having improved corrosion protection, wherein the coolant brines contain 0.2 to 5% by weight of alkali metal sulfites or pyrosulfites, in particular 1 to 2.5% by weight of these sulfites. The brines according to the invention furthermore contain 0.3 to 5% by weight of basic substances from the alkali metal carbonates, hydroxides, borates and phosphates group and also 0 to 0.3% by weight of alkali metal silicates and 0.02 to 0.2% by weight of stabilizers from the triazoles, benzimidazoles and/or mercaptothiazoles group. The novel coolant brines result in very low corrosion rates, in particular with steel and cast iron.
